Enhancement: Error handling for Place without Geometry

[ajolipa]

Currently, when a <PlaceMarker> component is passed a Core Data place with a null Geometry field, the entire page containing the map component fails to load, with console error Coordinates must contain numbers.

Ideally, failure to load coordinates from the Core Data API should trigger some sort of fallback behavior like just rendering a general world map, so that pages don't crash if this case somehow occurs.

May be a dupe of performant-software/core-data-cloud#164 (or vice-versa, as this issue is more specific)
